throughout the forest and the average size is small. The slippery 
elm tree grows to a height of from 60 to 70 feet, with a trunk rarely 
more than 2 to 2\ feet in diameter. The range of cork elm is much 
more limited than that of white and slippery elm (fig. 3). It does 
not extend farther south than Tennessee, and throughout a large part 
of the region of its distribution it is not important commercially. 
The tree attains a height of from 80 to 100 feet and a trunk diameter 
of from 3 to 4 feet. Wing elm grows in southeastern United States

rarely has a greater height than 60 feet or greater trunk diameter 
than 2 feet. Cedar elm occurs from southern Arkansas to Mississippi 
and in Texas. It reaches its best development in southern Arkansas 
and northeastern Texas, where it grows to a maximum height of 
90 feet and a maximum trunk diameter of about 3 feet. It is fairly
